Water filter jugs are a pretty straightforward product. You pour water into the chamber at the top of the jug, it trickles down through the replaceable filter cartridge, and the filtered water sits in the bottom part of the jug, ready to pour. It’s not the most essential item, but it has a clear and simple purpose, and provides some value: if you’re in a hard water area, it does make tap water taste less minging, and reduces limescale in other appliances like kettles and irons.
